Title: Polyimide and its production
Inventor: NOJIRI HITOSHI
IPC: C08G73/10
Filed: 1990-05-01
Abstract: PURPOSE:To obtain a polyimide excellent in moldability, heat resistance and mechanical properties by imidizing a polyamic acid obtained by reacting a diamine compound with a smaller molar amount of a nonlinear-structure tetracarboxylic acid dianhydride and reacting the product with a linear-structure tetracarboxylic acid dianhydride. CONSTITUTION:A polyamic acid obtained by adding a nonlinear structure tetracarboxylic acid dianhydride (A) (e.g. 3,3',4,4'-benzophenonetetracarboxylic dianhydride) in an amount smaller than the number of moles of a diamine compound (B) to a solution of the diamine compound (B) {e.g. 2,2-bis-[4-(4- aminophenoxy)phenyl]propane}, sufficiently reacting them, adding a linear- structure tetracarboxylic acid dianhydride (C) (e.g. pyromellitic dianhydride) in an amount to give the total number of moles of the dianhydrides which is substantially equal to that of the diamine compound to the reaction mixture, and sufficiently reacting them is imidized. A polyimide having structural units of the formula (wherein R<1> is a residue of compound A; R<2> is a bivalent residue of compound B; and R<3> is a residue of compound C; and x is a natural number) can be produced. This polyimide is excellent in moldability and heat resistance and has good mechanical properties.

Filed: 1989-05-08
Abstract: PURPOSE: To provide highly accurate current measurement over a wide range by generating an output signal including a digital signal generated by an A/D converter and a scale factor produced so as to have a relation to selected reference voltage. CONSTITUTION: The gain of a programmable amplifier 33 is controlled with a signal sent by a micro-controller 15 through a line 35. The amplifier used in this example involves four different gains 1, 1/2, 1/4, 1/16. The amplifier 33 is provided with a means 37 which generates an over-range signal sent to the micro-controller 15 through a line 39 if the output of the amplifier exceeds prescribed critical limit. To digital-measure the magnitude of electric current Ip with the maximum resolution, the micro-controller 15 selects a signal converted by an A/D converter to either of V1 or V2 and selects the reference voltage of the converter and the gain of the amplifier 33.

Title: Ptc thermistor heating device
Inventor: KAIMOTO TAKASHI
IPC: G05D23/24
Filed: 1992-05-08
Abstract: PURPOSE:To use a device for a long life even in the case of applying high voltage by eliminating generation of a problem of chip and crack in an element due to stress of thermal expansion and contraction, and improving flash withstand voltage. CONSTITUTION:A pair of parallel electrode 2a, 2b are helically formed in at least one surface of a PTC thermister element 1. Since a resistance value of the electrode is increased higher in accordance with approaching near a central part of the PTC thermister element, a current is allowed to easily flow in the vicinity of the periphery of the PTC thermister element and prevented from a little easily flowing in the vicinity of the center. On the other hand, since joule heat generated by electrification has a tendency to be easily confined in the vicinity of the center and to easily escape in the peripheral part, the current balance with the heat to uniformly heat a total unit of the element.

Title: Control system for paper-feeding in thermal printer
Inventor: TAKEDA KOUICHI
IPC: B41J19/76
Filed: 1980-08-25
Abstract: PURPOSE: To prevent skipping of printing by braking paper-feeding when a printing start signal for a succeeding line is provided before printing of a full line is completed, by a method wherein magnetic substances, being controlled by an electromagnet, are embedded in a position-detecting disc secured to a rotary shaft of a paper feed motor.  
     CONSTITUTION: A slit 15 is provided in a nonmagnetic disc 10 secured to a rotary shaft of a paper feed motor 2, and magnetic substances 12 are embedded in a part of the disc 10. If a photointerruptor 11 detects the slit 15 in the disc 10, the signal is sent to a control circuit 16, and a printing information for one full line is fed to thermal head 8. In case the thermal head 8 does not complete printing for one full line, a current is flowed from a circuit 16 to a coil 14 to absorb the magnetic substances 12 in the disc 10. This causes braking of the motor 2, and as a result, prevents print-skipping of a dot due to mismatching.

Abstract: PURPOSE:To prevent the generation of cracks in sealing resin and the exfoliation of resin by performing solder plating on the rear of a pad part, of a lead frame, which mounts a semiconductor chip. CONSTITUTION:After a lead frame 1 is positioned on a die 6, a punch 9 is made to descend, and the lead frame 1 is sandwiched by an upper mask 7 and a lower mask 8; while, in this state, plating liquid is made to flow from the arrow (a) direction to the arrow (b) direction, a current is applied to the lead frame 1, thereby performing plating on the lead part. Since apertures are formed on the punch 9 and the mask 7, the rear 5 also is plated. A semiconductor chip is mounted on the pad part of the lead frame 1, and wire-bonded to the lead tip of the lead frame 1. Then resin sealing is performed. As a result, the adhesion between the lead frame and the sealing resin is improved because of the softness and the surface roughness of solder. Thereby the generation of cracks in the sealing resin and the exfoliation of resin can be prevented.
